A public address system (PA system) is an electronic amplification system with a mixer, amplifier and loudspeakers, used to reinforce a sound source, e.g., a person giving a speech, a person giving an annoucment, a DJ playing prerecorded music, and distributing the sound throughout a venue or building.
PA systems with a larger number of speakers are widely used in institutional and commercial buildings, to read announcements or declare states of emergency.
Simple PA systems are often used in small venues such as school auditoriums, churches, and small bars. PA systems, which are often used in schools, also have microphones or intercoms in each room so that the occupants can reply to the central office, so for example the principle gives his/her message and teacher can talk directly back to the principle although not to the entire system.
The simplest PA systems consist of a microphone, a modestly-powered mixer amplifier and one or more loudspeakers, Simple PA systems of this type, often providing 50 to 200 watts of power, are often used in small venues such as school auditoriums, churches, and small bars.
A sound source such as a CD player or radio may be connected to a PA system so that music can be played through the system. PA systems can be basic or advanced, AES can provide any size system that can be adapted to fit a variety of needs.
